Abstract |
In an effort to gain knowledge of the fundamental emissions behavior of gasoline engines in HDV applications, a nine-truck evaluation of an experimental 23-mode test procedure was conducted, using both stationary- and chassis-operated engines. The characterization studies determined that power output level consistently influenced all emissions more than any other variable and illustrated the need to measure emissions at increments approaching 10- to 15-percent power intervals. Both stationary and chassis dynamometer versions of the experimental 23-mode test procedure was found to be workable with excellent run-to-run repeatability and satisfactory chassis-to-stationary agreement. The project generated a large body of data that is summarized in the report and included in some detail in a number of appendices. (Modified author abstract) |
